환경 규제로 급격히 줄고 있는 PVC 사용과 관련해 자동차에서의 사용을 규제해야 한다는 의견과 관련해 김필수 대림대 교수의 이야기를 들어봤다.
PVC contains chlorine, serious harm to human body
As automotive regulations become more important, TPE materials are in the spotlight

Regulations on various compounds that cause environmental pollution are becoming more stringent.
In particular, plastics are inevitably used, but no matter how environmentally friendly they are disposed of after they are manufactured, they eventually turn into microplastics and accumulate in our bodies, causing various diseases and playing a central role as a source of environmental pollution.
It may be the right answer to not produce plastic products at all. This means that various regulations are also being strengthened.
Among these, the use of polyvinyl chloride, also known as PVC, is rapidly decreasing due to its impact on the human body and its role as an environmental pollutant.
PVC contains chlorine, so if it burns in the natural environment, it causes serious environmental pollution and harm to the human body, making it even more serious.
The results of a combustion test of PVC by an authorized testing agency are so serious that a lethal amount of hydrochloric acid gas is generated.
An even bigger problem is that since PVC is rigid, phthalate plasticizers are often added to give it flexibility, but these compounds act as environmental hormones.
Over time, PVC products are slowly released and spread into the air, polluting indoor air quality and increasing human harm through environmental pollution and physical contact.
In particular, the trend is to further strengthen regulations on PVC products used in children's toys, medical tubing products, food packaging, etc., as they directly affect the human body.
Especially in the case of automobiles, the importance of regulation is even greater.
As automobiles are a field where the importance of passenger safety and indoor environment during travel time is increasingly emphasized, it is most important to build a more eco-friendly and human-friendly system.
Accordingly, standards for safety devices and materials used are being strengthened, and manufacturers' efforts to reflect this are also increasing.
However, since there are approximately 30,000 automobile parts and the materials and materials used are diverse, it is a field in which it is difficult to establish institutional standards for each individual part.
In the case of new cars, consumers also experience side effects due to various volatile odors, such as the smell of adhesive that vibrates inside the new car for a while, which is called new car syndrome. This is the situation.
Depending on the vehicle, some drivers may even suffer from this smell for years.
Manufacturers are increasingly using environmentally friendly materials for various indoor materials, and even for adhesives, there is a sharp increase in the use of environmentally friendly materials that do not have odor.
In particular, automobiles are subject to a wide range of temperature differences and rapid exposure, and are managed under the worst conditions, including extreme temperature, humidity, vibration, and aging. Therefore, the environmental friendliness of the materials used is of even greater concern.
The problem of PVC used in automobiles is not a problem of one or two days.
When PVC is used in the interior of a car, phthalate materials are often added, which naturally increases the problem of harmfulness.
The interior of a car is exposed to hot summer temperatures for long periods of time, and the harmful gases generated by PVC materials inside the car are very serious, as well as the harmful effects caused when the body comes into contact with them.
In particular, these materials are far from being environmentally friendly and their lifespan is affected as they crack or lose durability due to rapid temperature changes.
Among these automotive aftermarket products, the floor mats are said to be made of PVC material.
As it hardens in cold weather, it can crack, become deformed, and have poor durability. In addition, it is difficult to clean due to its heavy material, and its weight can affect fuel efficiency.
In particular, floor mats should ideally be made of a material that is flat on the floor and easy to clean, rather than a built-in structure that looks clean on the outside.
As various debris and other substances seep into the mat, it may appear clean on the outside, but in indoor circulation mode, various debris and harmful substances circulate inside the vehicle, causing atopic dermatitis and allergic respiratory diseases. Because it can cause trouble.
There are more than a few drawbacks here, such as problems with drying and the possibility of microbial growth due to moisture.
Naturally, the problem grows as the floor mats become the most problematic and messy area, as they generate bad odors and other issues.
Accordingly, TPE materials, which have recently been highlighted, are gaining attention as an environmentally friendly material that eliminates the various disadvantages mentioned above.
TPE material is called thermoplastic elastomer and is a material that has both the elasticity of rubber and the processability of plastic and is used in various industries.
It is a material that is used in various ways because it is not only environmentally friendly but also has excellent wear and cold resistance as well as shock absorption. Recently, its use is increasing even in the most difficult automobiles.
Floor mats made of this material are easy to clean and dry, and are also durable and convenient to use, making them increasingly popular.
When choosing floor mats and other car accessories, it would be better to consider consumer wisdom and cost-effectiveness when purchasing them.
In particular, consumers should become wise consumers who check for eco-friendly materials and purchase related automotive products.
